Background ইমেজকে fixed করা
সাধারনত যখন ইমেজকে repeat horizontally বা no-repeat করা হয় এবং নিচে অনেক টেক্সট বা অবজেষ্ট থাকে, তখন নিচের দিকে স্ত্রুল করতে থাকলে উপরের ব্যকগ্রাউন্ড ইমেজও স্ত্রুল হয়। এটি বন্ধ করার জন্য অর্থ্যাৎ টেক্সট বা অবজেক্ট ক্রল হবে কিন্তু ব্যাকগ্রাউন্ড ইমেজ নড়বে না, এজন্য background-attachment প্রোপার্টিজ এর সাথে Value দিতে হবে fixed নিচের মত প্রোগ্রাম তৈরী করে দেখুন।
